The PCA9548ADWR from Texas Instruments is an 8-channel bidirectional translating switch that facilitates communication between I2C and SMBus devices. It supports voltage-level translation between 1.8-V, 2.5-V, 3.3-V, and 5-V buses, making it versatile for mixed-voltage systems.
This device operates within a power-supply voltage range of 2.3 V to 5.5 V and supports clock frequencies up to 400 kHz. It features an active-low reset input and three hardware address pins, allowing up to eight PCA9548A devices to be used on the same I2C bus. The switch channels are deselected upon power-up, and it supports hot insertion.
The PCA9548ADWR is available in a 24-SOIC package, suitable for surface mount applications. Its design includes 5-V tolerant inputs and low R ON switches, ensuring reliable performance in various interfacing scenarios. The part is rated for an operating temperature range of -40°C to 85°C.
